NASA requests industry proposals for its canceled satellite refueling demo mission

9:14 am

NASA today issued a request-for-information, asking the commercial aerospace industry for “alternate use” ideas for using the “flight hardware, test facilities, and experienced personnel” of its canceled satellite refueling demo mission, dubbed OSAM.

The request suggests NASA is hoping a private company will pick up the mission at its own cost, thus getting it off NASA’s hands. The agency canceled it because it is almost a decade behind schedule, hundreds of millions of dollars over-budget, and has an absurd workforce of 450 people. The agency is also under pressure from the Senate not to cancel the project, because our idiotic elected officials like to make-believe that funding these make-work projects accomplishes something.

Even if a private company takes on the project, if it does so at its own expense that workforce is certain to be reduced, possibly as much as 90%. No commercial satellite company is going to get saddled with that cost. It will want NASA to pay the bill.

NASA confirms its giant solar sail is tumbling but doing so as planned

9:04 am

NASA today outlined the testing that its engineers are doing with the deployed 860 square foot Advanced Composite Solar Sail System (AC3), including the planned tumbling that an amateur astronomer detected based on the fluctuating brightness of the sail.

Currently orbiting Earth, the spacecraft can be seen with its reflective sails deployed from the ground. As part of the planned deployment sequence, the spacecraft began flying without attitude control just before the deployment of the booms. As a result, it is slowly tumbling as expected. Once the mission team finishes characterizing the booms and sail, they will re-engage the spacecraft’s attitude control system, which will stabilize the spacecraft and stop the tumbling. Engineers will then analyze flight dynamics before initiating maneuvers that will raise and lower the spacecraft’s orbit.

The release adds that NASA has added a feature to its mobile app that will help anyone spot the sail in the night sky.

Czech government signs deal with Axiom to fly astronaut

8:58 am

The Czech government and the American space station company Axiom have now signed an agreement to fly Czech’s ESA astronaut Aleš Svoboda on a future spaceflight.

No date for the mission has been set, nor is it clear whether it will be an orbital mission or will dock with either ISS or Axiom’s own station once launched. The release also said nothing about a launch vehicle or spacecraft for transporting Svoboda into space, though that vehicle will almost certainly be a Falcon 9 and a Dragon capsule.

China launches third batch of 10 satellites for proposed Starlink copycat constellation

8:51 am

China early this morning launched the third group of ten satellites for a proposed low-Earth-orbit internet constellation of nearly 6,000 satellites, proposed and built by a Chinese pseudo-company Geespace.

The company was created in 2018 and is backed by the Chinese automaker Geely. The Long March 6 rocket lifted off from China’s Taiyuan spaceport in northeast China. No word on where the rocket’s lower stages crashed.

The leaders in the 2024 launch race:

88 SpaceX
38 China
10 Rocket Lab
9 Russia

American private enterprise now leads the rest of the world combined in successful launches 103 to 57, while SpaceX by itself leads the entire world, including American companies, 88 to 72.

Fernando Ortega – Just As I Am

6:01 pm

An evening pause: A Christian’s prayer, set to beautiful music and performed live 2011. I post a lot of hard rock celebrating sex, drugs, and rock & roll, because the music and performance is great. I post this for the same reason. I wonder how many of my non-Christian readers will be open to listening and enjoying it.

Hat tip James Street.

Curiosity takes another look south into Gediz Vallis

2:18 pm

Looking south inside Gediz Vallis

Overview map
Click for interactive map.

Cool image time! As it has been more than a month since I lasted posted a cool landscape image from the Mars rover Curiosity, it seemed time to upload the panorama above, changed not at all to post here and taken by the rover’s right navigation camera on September 4, 2024.

The blue dot on the overview map to the right marks Curiosity’s present position. The yellow lines indicate the approximate direction of the panorama’s view. The red dotted line indicates Curiosity’s planned route, with the white dotted line marking its actual path. After spending most of the last month on a drilling campaign at the southernmost point of its travels, the science team had Curiosity retreat northward, where it will eventually head uphill to the west to swing around that mountain to head south in a parallel canyon.

The panorama looks into the slot canyon Gediz Vallis that Curiosity has been exploring for a little more than a year. The light colored mountains are what the scientists call the sulfate-bearing unit, a region on the higher slopes of Mount Sharp that is likely to have a very alien geology and chemistry, when compared to what is seen on Earth. Mount Sharp itself is beyond these peaks, not visible because it is about 26 miles away and blocked by these lower mountains.

Since landing on Mars a dozen years ago, the rover has traveled 20 miles and climbed about 2,500 feet. Getting to the top of Mount Sharp will therefore probably take more than one or two decades more of travel.

A former Democratic Party majority leader in California sees the light

1:33 pm

The Democratic Party today
The Democratic Party today

If she of all people can do this, why can’t so many other ordinary Democrats? Gloria Romero, former Democratic Party majority leader in the California state senate from 2005 to 2008, announced publicly yesterday that she has dumped her lifelong allegiance to that party, switched her registration to the Republican Party, and furthermore enthusiastically endorsed Donald Trump for president. From her statement:

“Today I say ‘goodbye, adios,’ I’ve had enough. I am now another near-lifelong Democrat who is joining the growing number of people, including key groups like Latinos, who are leaving the Democratic Party. This is not the Democratic Party that I once championed. I do not recognize it anymore, and I cannot continue. I changed my voting registration today as the sun was rising to Republican, which has, under Donald Trump, become the champion of working people, the big tent. And indeed, I will vote for Donald Trump this fall.”

She proceeded to list the many tyrannical actions taken by the Democratic Party recently that led her to this decision, including its backroom deals that blocked any others from running against Joe Biden during the presidential primaries and then dumped him for Kamala Harris. She also cited that party’s support for the queer agenda, for “locking people up for free speech,” for supporting “endless war” everywhere, and for allowing an invasion of illegal immigrants, including violent felons.

Above all she cited the Democratic Party’s failed school policies, from favoring the school unions that do not educate kids but funnel money into the party’s campaign coffers to encouraging anti-Semitism at universities. “The Democratic party thrives off of this failure shamefully … even as our children fall farther and farther behind in reading, writing and the ability to compete internationally.”

None of her criticisms of the Democratic Party are wrong. » Read more

Woman arrested at Arizona city council meeting for exercising her 1st amendment rights sues

Rebekah Massie, the woman who was arrested two weeks ago while attempting to speak during the open comment period at the city council meeting in Surprise, Arizona, has now sued the town’s mayor Skip Hall, the policeman who arrested her, and the city council for violating her 1st amendment rights.

The lawsuit, filed by her attorneys at the Foundation for Individual Rights and Expression (FIRE), can be read here. From FIRE’s press release:

FIRE’s lawsuit aims to permanently stop enforcement of the city policy used to silence Rebekah and obtain damages. In the meantime, FIRE moved for a court order to stop the city’s use of the policy while the lawsuit is pending. The lawsuit names the City of Surprise, Mayor Hall, and Steven Shernicoff, the officer who arrested Rebekah, as defendants. Quintus Schulzke, a Surprise resident who frequently makes public comments at city council meetings, also signed on as a plaintiff. Without legal intervention, Schulzke — or any other member of the public — risks arrest simply for speaking his mind to his elected representatives.

I have embedded the video of Massie’s arrest below. When I first reported this story I suggested Massie find a good lawyer and sue. It is great she wasted no time doing so. Even better, she is personally suing the mayor and the police officer who arrested her, and demanding punitive damages.

Mars loses hydrogen at very different rates, depending on the planet’s distance from the Sun

11:37 am

Hubble uv images of Mars atmosphere
Click for original image.

Scientists using data from both the MAVEN Mars Orbiter and the Hubble Space Telescope have determined that the rate in which Mars loses hydrogen and deuterium varies considerably during the Martian year, with the rate going up rapidly when the red planet reaches its closest point to the Sun. The picture to the right, reduced to post here, shows the data from Hubble.

These are far-ultraviolet Hubble images of Mars near its farthest point from the Sun, called aphelion, on December 31, 2017 (top), and near its closest approach to the Sun, called perihelion, on December 19, 2016 (bottom). The atmosphere is clearly brighter and more extended when Mars is close to the Sun.

Reflected sunlight from Mars at these wavelengths shows scattering by atmospheric molecules and haze, while the polar ice caps and some surface features are also visible. Hubble and NASA’s MAVEN showed that Martian atmospheric conditions change very quickly. When Mars is close to the Sun, water molecules rise very rapidly through the atmosphere, breaking apart and releasing atoms at high altitudes.

From this data scientists will be better able to map out the overall loss rate of water on Mars over many billions of years.

China significantly expands its international partners for its planetary program

10:34 am

According to China’s state-run press, it has recently signed cooperative agreements with a significant number of new nations for either its International Lunar Research Station project (ILRS) or other deep space planetary missions.

During the opening ceremony of a two-day space conference held in Tunxi, east China’s Anhui Province on Thursday, the China National Space Administration (CNSA) and its counterpart in Senegal signed an agreement on International Lunar Research Station (ILRS) cooperation.

At the conference, China’s Deep Space Exploration Lab (DSEL) inked memoranda of understanding with 10 institutions from countries including Serbia, Switzerland, the United Arab Emirates, Indonesia, Pakistan, Panama and South Africa. Also among the institutions are the Belt and Road Alliance for Science & Technology, the Foundation for Space Development Africa, and Africa Business Alliance.

Senegal is now the thirteenth nation to join China’s lunar base project, following Azerbaijan, Belarus, Egypt, Kazakhstan, Nicaragua, Pakistan, Russia, Serbia, South Africa, Thailand, Turkey, and Venezuela. That partnership also includes about eleven academic or governmental bureaucracies.

The agreements involving China’s deep space exploration involve other missions to other planets, with those nations either providing science instruments or some other contribution. That Switzerland and the United Arab Emirates have signed deals suggests there is a rising desire in the west to team up with China because of its general success in space, compared to the problems other nations often experience when dealing with NASA and the U.S. If so, the competition will certainly heat up in the coming years. I hope in this competition that American private enterprise can make up for the failures of our government.
